It should work if you call TakeDamage() with the damage property, how do you know its not working? Is the function beeing called? Try this to check:

public void TakeDamage(float damage)
     {
         Debug.Log("hp before: " + hitPoints + "  - " +damage);
         hitPoints -= damage;
         Debug.Log("after: " + hitPoints);
         if (hitPoints <= 0)
         {
             Debug.Log("You dead, my glip glop");
         }
     }
